Google Analytics is an invaluable source of data on just about every conceivable aspect of your site, from your most popular pages to visitor demographics. Keep a close eye on your Analytics data, and use this information to inform your promotional and content strategies. Pay attention to what posts and pages are proving the most popular. Inspect visitor data to see how, where and when your site traffic is coming from.
Hey Ted, thanks for the great questions! The peak times refer to your particular time zone, if you are targeting an audience that resides in the same zone as you. You can also use tools to find out when most of your audience is online. For example, Facebook has this built into their Page Insights. For Twitter, you can use https://followerwonk.com/. Many social posting tools also offer this functionality.
